Supporting components include an inlet filter, an outlet silencer, a vent valve, and an exhaust‑port assembly. Each part performs its designated function while working in seamless synergy to form a fully integrated operating system.

1. Core working component: high-speed three-dimensional flow impeller

The impeller is the core working component of a fan, responsible for generating airflow pressure and volume, and directly determines the fan’s efficiency and the stability of its air delivery. The equipment employs… High-speed three-dimensional flow precision impeller Unlike the conventional planar air‑delivery structure of two‑dimensional impellers, this design leverages three‑dimensional computational fluid dynamics (CFD) simulations to optimize blade geometry. The curved surface of the blades conforms to the airflow trajectory, thereby minimizing aerodynamic drag and reducing turbulence‑related energy losses.

The impeller is crafted from high‑strength, aerospace‑grade aluminum alloy and precision‑machined on a five‑axis machine, delivering exceptional strength, lightweight construction, corrosion resistance, and deformation resilience. Paired with the motor’s ultra‑high‑speed operation, it rapidly compresses air to generate a stable, high‑pressure airflow, achieving far superior ventilation efficiency compared to conventional blowers.
